A new module is required because both strerror and strerror_r might
need strerror-override.o, but they might be in different directories
(one in lib and one in tests), and we can only AC_LIBOBJ it once.
Now, just the strerror module in isolation does not drag in strerror_r.
Tested on glibc with:
gl_cv_header_errno_h_complete=no gl_cv_func_working_strerror=no \
gl_cv_func_strerror_r_works=no ./gnulib-tool --with-tests \
--test strerror strerror_r-posix
Hmm, perhaps I should move strerror-override.c to be part of the
errno module, rather than making it a separate module. That is,
the only time the strerror_override() function should be compiled
is if our replacement errno.h added new values.
